title: Sarcocystis species in moose (Alces alces), bison (Bison, bison), and pronghorn (Antilocapra americana) in Montana.
abstract: The transmission of Sarcocystis spp from naturally infected moose, bison, and pronghorn was attempted in laboratory-raised coyotes and dogs. Infected musculature from a moose was feed to a dog and a coyote, and 12 days later, both animals shed sporocysts. Sporocysts were 14 to 17 X 8.5 to 10.5 micron (av 14.5 X 8.8). A coyote was fed muscle from a bison, and 11 days later, it shed sporocysts. The sporocysts were 14 to 16 X 9 to 11 micron (14.0 X 9.0). Infected tissues from a pronghorn were fed to a dog; the dog did not shed sporocysts. Two morphologically distinct sarcocysts (thick walled and thin walled) were found in masculature of a moose. The name, Sarcocystis alceslatrans, sp n, is proposed for the thin-walled sarcocysts in the mouse.
